8.5 is ideal so I wouldn't worry too much about 8.6
I doubt if it'll stay that high after a month or so. You should test your alkalinity and calcium levels to make sure you have the reactor tuned to the parameters that your tank requires.

Gonna raise my CO2 bubble rate to set my effluent ph at about 6.5-6.8. Then I'm going to lower the effluent drip rate and see if that corrects the problem.
I think I caused an acidic condition within the reactor causing the high PH swings. Right now my effluent ph is about 7.1. I was trying to adjust my Alk and Cal levels down a little bit, but I think I went about it the wrong way causing another problem.
